CVE-2025-25083

Vulnerability

Overview

CVE-2025-25083 is a stored cross-site scripting (XSS) vulnerability in the Dave Lavoie EP4 More Embeds WordPress plugin, affecting versions through 1.0.0. The issue stems from improper neutralization of input during web page generation, allowing user-supplied data to be stored and later executed in the context of other users' browsers [1].

Exploitation

Exploitation requires a privileged user (e.g., an editor or admin) to submit crafted input that is not properly sanitized. This input is then stored and displayed to other users, including site visitors. A privileged user must first perform an action such as clicking a link or visiting a crafted page; however, the stored XSS payload can subsequently affect any user who views the compromised page [1].

Impact

Successful exploitation allows an attacker to inject arbitrary HTML and JavaScript into the website. This can lead to redirects, display of advertisements, theft of session cookies, or other malicious actions performed in the browsers of visitors [1].

Mitigation

As of the publication date, no official patch is available. Users are advised to update the plugin as soon as a fix is released or apply a mitigation rule, such as those provided by Patchstack, which can block attacks until an official update is deployed [1].
